Developing multigenerational products through iteration helps enterprises cope with environmental uncertainty and maintain lasting competitive advantages in a globally competitive environment. From the knowledge integration perspective, this study aims explore how enterprises achieve multigenerational product innovation.

An exploratory case study design is used to explore the multigenerational product innovation process.

This study proposes a model of the multigenerational product innovation process and shows that knowledge integration includes two important parts: the internalization of external knowledge and intergenerational knowledge integration. This study further conclude that multigenerational innovation has three main channels: rapid iteration, continuous reflection and coordination.

First, this study presents a theoretical model of the process of multigenerational product innovation, including triggers, knowledge integration, learning systems and outcomes, and further enhances our understanding from product innovation to multigenerational product innovation. Second, this study contributes to the literature on the multigenerational product innovation process by revealing the knowledge integration process of the internalization of external knowledge and intergenerational knowledge integration.

The purpose of this paper is to artificially construct a functional surface with self-propulsion flow characteristics for the directional transportation of propellant in surface tension tanks.

In this study, a method to enhance the propulsion efficiency by using functional surfaces of self-propulsion performance was proposed. Superhydrophilic wedged-groove with the superhydrophobic background was fabricated and the self-propulsion capacity was verified.

It is found that the self-propulsion capacity is related to the divergence angle of the wedged-groove in the hydrophilic area, and the velocity of the droplets on the deflector plate is the largest with the divergence angle of 4°; the temperature gradient field formed by the condensing device at the nozzle can accelerate the droplet outflow from the tank.

Realization of this idea provides an accurate control strategy for the complex flow process of propellant in plate surface tension tanks, which could enhance the efficiency of the tension tank significantly.

The purpose of this paper is to provide the historical and social contexts for the three protests in Macau in the Summer of 2014, while examining the popular discourse of the protests. These include simultaneous eruptions toward immediate issues, the political apathy of Macau residents and Castell’s model of “networked social networks.” It also discusses the competition for youth after the protests.

This paper first reviews the history of Macau, in particular the people’s struggle against corruption and privilege, and its little-discussed history of protest. Its innovation in communications, political structure and education development are also explained to illustrate the foundations which make possible protests against an obsolete social structure.

The author finds that the history of Macau since the nineteenth century does not lack protests, with goals ranging from protests against colonialism to national and local demands. Macau youth are now more able and willing to mobilize themselves to make demands on the administration, and activists find it necessary to pass down such experience for generations to come.

The paper deconstructs the traditional image of Macau’s politics, by appealing to the linkage between continuity and contemporary events, and calls for the reader’s attention toward its social activism.
